SOFA BED.

Application filed April 9,

This invention relates particularly to a combination sofa and bed; andthe primary object of the invention is to provide a cheap and simpleconstruction which is well adaptview showing the structure in bed-form;Fig.

construction.

2, a broken plan sectional view taken as indicated at line 2 of Fig. 1;Fig. 3, a broken plan sectional view taken as indicated at line 30f Fig.1; Fig. 1, a View similar to Fig.1, but showing the front bed-sectioncollapsed and in readiness to be shoved into the folded position; Fig.5, a broken plan section taken as indicated at line 5 of Fig. 4; Fig. 6,a broken vertical section taken as indicated at line 6 of Fig. 1; Fig.7, a broken section taken as indicated at line 7 of Fig. 1 and showing aguide-bar employed; and Fig. 8, a broken vertical sectional view takenas indicated at line 8 of Fig. 1.

In the construction illustrated, A designates the main frame of thesofa-bed; B, a rear bed-section fixedly mounted in said frame and whichis adapted to serve also as a seat;

nd C, a front bed-section collapsibly mounted upon a sliding frame Cwhich is connected with guides C (one shown), with which the lowerportion of the main frame A is provided.

. The main frame A ma be of any suitable In the il ustration given, itcomprises end-standards 1 (one shown) connected by longitudinal members2-which serve as the base for the bed-section B.

The bed-section B is shown as comprising conical springs 23 supportedupon the base 2 and alfording a foundation fora mattress, or cushion,(not shown).

The front bed-section G is shown as comprising a rectangular frame 1which supports conical springs 5 affording a foundation for a mattress,or cushion, (not shown). The slidable supporting frame C for the frontbed-section consists of a rectangular frame composed of end-members 6and longitudinal connecting members 7 and 8. The front member 7 hassecured thereto a front piece 9 which is adapted to be housed beneaththe front member 2 of the main frame when the structure is in sofa-form.

The end-members 6 of the sliding frame 1926. Serial No. 100,899.

C have secured thereto guide-bars 10 (Fig. 7) which extend parallel withthe end-members 6 and secured thereto by rivets 11. An interveningspacer member 12 preferably'is employed. The spacer, or spacers, 12rests on the guide C and the guide-bar 10 is disposed back of the guideC as indicated by dotted lines in Fig. 6. The slide is held in the guideby means of a bar 13 which is secured to the end-member 1.

The bed-section C has its frame portion 4 mounted on parallelv links 14and 15 which, it will be understood, are duplicated at the two ends ofthe structure. of said links are pivotally connected with the end-member6 of the slidable frameC. The upper portions of said links are connectedby pivots l6 with-slides 17 mounted on the endmembers of the frame 4.The slides 17 are cd'nnected by a link 18 whose end-portions areconnected with the pivots 16. i

The front links, or arms, 15 are provided at their upper ends withextensions 19 which serve as handles. The extensions 19 are shownconnected by a rod or shaft, 20. The extensions 19 project forwardly andupward ly, assuming the structure to be in bed-form.

The frame 4; of the bed-section C is equipped with depending lugs 21with which are connected levers 21 which are pivotally connected at 22with depending lugs carried bythe front portions of the end-members 6 ofthe frame C". Counterbalancing springs 23 connect the short arms or legsof the levers 21 with the sliding frame C.

A stop-bar 24 is secured to the rear memher 8 of the frame 0' and servesto limit the forward movement of the frame C by strikin" stops 24.

hen the structure is in bed-form, the 9 links 14 preferably inclineforwardly somewhat, so that there will be no danger of the frontbed-section collapsing under the weight of an occupant. The rear links14 are connected with the end members of the frame C: by pivots 25. Thefront links 15 The lower ends are pivotally connected with theend-members 6 through the medium of a longitudinal bar 26, whichpreferably is of square cross-section. As shown in Fig. 8, the endportion of the bar 26 enters a squared erforation in a boss 15 withwhich the lin or lever, 15 is provided. The boss is provided with acircular bearing portion 15 whieh is free to turn within a bearingperforation with which the frame-member 6 is provided. The boss 15 isconfined between the vertical flange of the member 6 and a collar 27 onthe bar 26, said collar being held in place by lugs 28 formed by cuttingor striking the metal at the corners of the bar.

The manner in which the improved structure operates will be readilyunderstood from Fig. 1. An operator may grasp the handle 20 and swingthe link 15 rearwardly. This results in causing the slides 17 to moverearwardly and lower the front bed-section to the position shown in Fig.4:. The collapsed bedsection may then be-shoved rearwardly and housedwithin the main frame beneath the rear bed-section. The reverseoperation of converting thestructure from sofa-form to bed-form isobvious.

It will be understood that the parts may be suitably separated so thatspace will be provided between the front bed-section and the superposedrear bed-section for bedding, if desired; also, that the rod, or handle,20., will, in the collapsed condition of the front bed-section, projectover any bedding; which may be left upon the front bed-section G. Also,it will be understood that suitable mattresses, or cushions, may beemployed in connection with the structure. The fixed bedsection B servesas a seat when the structure is used for sofa purposes, the cushionsbeing superposed upon the springs 3.

When the structure is in extended position, the front rail of the frame4 may be disposed above the front piece 9. When the collapsing actionoccurs, the levers 21 cause a short rearward movement of the frame a, sothat the bed-section C settles down into position back of thehousing-member 9 and in collapsed relation with respect to thesupportaviaiee ing-frame G. The slidable frame C may then be shovedrearwardly until the front housing-member 9 enters the space beneath thelongitudinal member 2 of the main frame.

The foregoing detailed description has What I regard as new, and desireto secure by Letters Patent, is:

l. A sofa-bed comprising a main frame, a rear bed-section mountedtherein and adapted to serve as a seat, guides mounted in said frame ata distance below said rear bedsection, a horizontal slidable framemounted in said guides, links mounted on said horizontal frame, afrontbed-section having a frame equipped with slides mounted on said links, alink connecting said last-nai'ned frame with said slidable frame andequipped with an arm adapted to serve as a leg, and a counterbalancingspring connecting said arm with said slidable frame.

2. In a sofa bed having a forwardly slidable frame carrying abed-section, means for raising said bed section and supporting the samein raised position, said means including links pivotally mounted on theend members of the slidable frame and adapted to swing forwardly andupwardly in raising the bed section, two of the links on opposite endsof the frame equipped with extensions joined by a handle lying over thebody section, slide carried by the bed section and ivotall'y cor. nectedwith the links, and lin (s connecting; the slides.
